A universal life insurance policy can be described most accurately as a combination of:

Universal life insurance is a flexible product that combines features of term insurance and a savings component:

Flexible premium deposit fund and a monthly renewable term insurance policy (D): Universal life allows policyholders to adjust premiums and coverage amounts. The policy includes a savings element (cash value) and provides renewable term insurance protection.

Mutual fund and whole life insurance policy (A): Incorrect, as universal life does not involve mutual funds or strict whole life coverage.

Term insurance and an annuity (B): Universal life lacks the payout structure of an annuity.

Endowment and interest-sensitive deposit fund (C): While it includes interest-sensitive growth, it is not structured as an endowment policy.
